Possible Causes

Loose hose clamp, Split dishwasher hose, Inlet spigot not fully opened (knockout partially removed), Damaged inlet nipple

How to Fix / Troubleshooting

Safety first: Turn off power to both disposal and dishwasher.

  • Tighten clamp: Use a screwdriver to tighten the hose clamp at the disposal inlet.
  • Inspect hose: Look for splits or pinholes near the clamp. Replace the hose if damaged.
  • Verify knockout: If recently installed, ensure the knockout plug was fully removed from the inlet. A partially removed plug can cause leakage and poor drainage.
  • Test cycle: Run a short dishwasher cycle and operate the disposal with water to confirm no leaks.
